Description

경량결합제(Lightweight Joint Compound)Lightweight Joint Compound

본 발명은 인접한 석고벽판(gypsum wallboard)사이의 이음매(joint)를 메우고 도포하는데 사용하기 위한 결합제에 관한 것으로, 특히 통상의 결합제보다 중량이 가벼우며 모래치기(sandability) 에 보다 좋고 운송비용이 절감되고 콘테이너조작 및 도구이용이 용이하며 마지막 모래질(sanding) 및 벽판이음매의 마무리에 용이한 결합제에 관한 것이다.FIELD OF THE INVENTION The present invention relates to a binder for use in filling and applying joints between adjacent gypsum wallboards, and in particular, is lighter in weight than conventional binders, better sandability and reduced transportation costs. It relates to a binder that is easy to operate and tool and is easy to finish sanding and finishing of wallboard joints.

빌딩건축에 있어서, 가장 보편적인 요소의 하나는 벽 및/혹은 천정공사에 사용되는 통상적으로 "건조벽(dry wall)"이라고 알려져 있는 석고벽판이다.In building construction, one of the most common elements is gypsum wallboard, commonly known as a "dry wall" used for walls and / or ceilings.

석고벽판으로 만들어진 벽은 통상적으로 패널을 샛기둥이나 이음매에 붙이고 "결합제(joint compoumd)" 라고 불리우는 특별히 제조된 접착제로써 이음매를 채우고, 도포하므로써 이루어진다. 이 공정은 대개 다음 형태로 진행한다.Walls made of gypsum wallboard are usually made by attaching panels to a jaw or seam and filling and applying the seams with a specially prepared adhesive called "joint compoumd". This process usually proceeds in the following form.

즉, 테이핑결합도의(taping grade)결합제를 벽판의 인접 가장자리에 의해 형성된 이음매내부에 놓고, 액체투과가능한 테이프를 테이핑결합제 내부에 채운다.That is, a tapping grade binder is placed inside the seam formed by the adjacent edges of the wallboard, and the liquid permeable tape is filled inside the taper binder.

건조되면(혹은 응결되면), 토핑 결합도의(topping grade)결합제를 포함하는 2차도포가 이음새위에 행하여진다. 가볍게 모래질이 된뒤 3차도포가 행하여지며 통상적방법으로 마무리 된다.Once dried (or condensed), a secondary coating containing a topping grade binder is made on the seam. After being lightly sanded, tertiary application is carried out and finished in the usual way.

다른 결합도의(Grade) 결합제는 테이프 매립(embedding)및 마무리도포로써 사용되는 문자그대로 다목적의 것이다. 몇몇 경우에 있어, 무늬효과가 마무리된 벽에 주어지면 다목적 결합제와 합하여 그결과 질감있는 마무리(textured finish)를 제공한다. 과거에 있어서 결합제의 여러결합도(grade)사이의 일차적인 차이는 성분요소의 조성비의 차이에 있었다.Other grade binders are literally versatile, used as tape embedding and finishing applications. In some cases, when a patterning effect is given to a finished wall, it combines with a multipurpose binder to provide a textured finish. In the past, the primary difference between the different grades of binders was the difference in the composition ratio of the components.

어떠한 결합도에 있어서도 결합제는 항상 충진재와 접착재를 포함한다. 테이핑 결합도에서는 토핑 결합도에서보다 더많은 접합제가 사용된다. 전형적인 충진재는 탄산칼슘, 칼슘 설페이트 헤미하이드레이트 혹은 칼슘설페이트 디 하이드레이트이다.In any bond, the binder always includes filler and adhesive. In the taping bond more binder is used than in the topping bond. Typical fillers are calcium carbonate, calcium sulfate hemihydrate or calcium sulfate dihydrate.

명백한 선택은 결합제가 건조에 의해 견고해지느냐 아니면 응결에 의해 견고해지느냐에 따라 결정된다. 응결형 결합제의 예는 미국특허 제3297601호에 나와있다. 미국특허 제Re29753호에서의 결합제는 석면이 제기되고 석면섬유의 사용에 의해 미리 얻어진 비평준성(non-leveling properties)을 제공하기 위하여 점토(attapulgus clay)를 사용하는 것으로 알려져 있다. 점토(attapulgus clay)를 사용한 혹은 사용하지 않은 종래의 결합제는 성능면에서는 우수하나 이들은 중량이 매우 무거우며 운송비가 많이든다. 또한 이들은 건조될때 단단한 질감을 가지며 매끈한 표면을 가진 이음새처리를 제공하기 위한 모래질이 어려운 것이다. 따라서 종래의 결합제보다 가볍고, 건조시 매끈한 표면을 제공하기 위하여 모래질이 쉽게되는 결합제가 요구되는 것이다.The obvious choice depends on whether the binder is hardened by drying or by condensation. Examples of coagulating binders are found in US Pat. No. 3297601. The binder in US Pat. No. Re29753 is known to use clay to provide asbestos and to provide non-leveling properties previously obtained by the use of asbestos fibers. Conventional binders with or without clay clay are excellent in performance but they are very heavy and expensive to transport. They are also difficult to sand to provide seams with a smooth texture and smooth surface when dried. Therefore, there is a need for a binder that is lighter than a conventional binder and that is easily sanded in order to provide a smooth surface when dried.

본 발명의 목적은 석면이 제외된 결합제를 제공하는 것이다. 또한 일반적으로 결합제에 요구되는 비평준성, 비균열성(non-cracking) 및 양호한 접착성 같은 뛰어난 성질을 가진 결합제를 제공하는데 있다. 또 다른 본 발명의 목적은 종래의 결합제보다 중량이 가볍고 저렴한 가격으로 운반가능한 결합제를 제공하는데 있다. 또한 건조후 매끈한 마무리를 위하여 쉽게 모래질되는 형태의 결합제를 제공하는데 있다.It is an object of the present invention to provide a binder without asbestos. It is also to provide a binder having excellent properties such as non-leveling, non-cracking and good adhesion generally required for the binder. Another object of the present invention is to provide a binder that is lighter in weight than the conventional binder and can be transported at a lower price. It is also to provide a binder of the easily sanded form for a smooth finish after drying.

비균열성 및 뛰어난 접착성을 제공하는 것은 부가적인 목적이다. 본 발명의 제목적 및 장점들은 다음 기술을 참고로 명백하게 될 것이다. 본 발명에 따라서, 탄산칼슘, 칼슘 설페이트 디하이드레이트 또는 칼슘설페이트 헤미하이드레이트와 같은 충진재, 폴리비닐아세테이트와 같은 접합재, 점토(attapulgus clay)와 같은 비평준화 및 슬립제공물질, 하이드록시프로필메틸셀룰로우즈와 같은 보수제 또는 농조화제 및 특수처리된 팽창퍼얼라이트(expanded perlite)를 포함하는 조성을 조형화함에 의하여 석면이 필요없는, 매우 가벼운 중량의 신규결합제가 제공된다.Providing non-crackability and good adhesion is an additional object. The title and advantages of the present invention will become apparent with reference to the following description. According to the present invention, fillers such as calcium carbonate, calcium sulfate dihydrate or calcium sulfate hemihydrate, binders such as polyvinylacetate, non-leveling and slip-providing materials such as claypulgus clay, and hydroxypropylmethylcellulose By formulating a composition comprising a repair or thickening agent and a specially treated expanded perlite, asbestos-free new binders are provided that are asbestos free.

퍼얼라이트의 존재는 실제적으로 결합제의 밀도를 줄이며 운송비용을 절감케한다. 나아가 물과 혼합시 그 구성은 뛰어난 성질을 가진, 건조시 쉽게 모래질되어 매끈한 마무리를 가지는 결합제를 제공한다. 본발명 경량 결합제의 제1성분은 팽창된, 특수처리된 퍼얼라이트이다. 퍼얼라이트는 흑요석(黑曜石)과 비슷한 유리질암석형태이다. 일반적으로 이는 65-75% SiO2, 10-20% Al2O3, 2-5% H2O 및 소량의 소오다, 포타시(potash) 및 석회로 이루어져 있다. 퍼얼라이트가 연화점까지 가열되면, 이는 창팽하여 부석(浮石)과 비슷한 가벼운 솜털모양의 부풀은 물질을 형성한다.The presence of pearlite actually reduces the density of the binder and saves transportation costs. Furthermore, when mixed with water, the composition provides a binder having excellent properties, which is easily sanded upon drying and has a smooth finish. The first component of the lightweight binder of the present invention is an expanded, specially treated pearlite. Pearlite is a glassy rock form similar to obsidian. Generally it consists of 65-75% SiO 2 , 10-20% Al 2 O 3 , 2-5% H 2 O and small amounts of soda, potash and lime. When the pearlite is heated to a softening point, it expands and forms a light, fluffy, swelling material that resembles pumice.

본 발명에 사용하기 위한 퍼얼라이트제조에 있어 이것은 우선 크기가 -200메쉬(mesh)보다 미세하게 연마분쇄된다. 분쇄된 퍼얼라이트는 그 다음 약 1500℉의 온도로 가열된다. 이 공정은 퍼얼라이트 팽창기내에서 우선 공기를 1500℉까지 가열하므로써 행하여진다. 미세하게 연마된 퍼얼라이트는 그 다음 가열공기속으로 도입된다. 가열공기에 의해 운반되면서 이는 가열되고 팝콘같이 튀겨진다. 팽창 퍼얼라이트는 아주 가벼운 물질이다. 그러나 이것은 많은 미세한 홈 및 갈라진 틈이있다. 그리고 물에 닿게되면 물이 이 홈및 갈라진 틈으로 침투해들어가서 퍼얼라이트의 공기로 가득찬 공동(空洞)으로 들어간다. 따라서, 팽창 퍼얼라이트를 결합제로 만드는데 사용하기 이전에 이것은 우선 물에 영양받지 않도록 처리되어야 한다. 이는 여러가지 방법중 한가지로 행할수가 있다. 바람직한 방법은 팽창 된 퍼얼라이트를 균열이나 틈새를 막는 실리콘화합물로 처리하는 것이다.In the production of pearlite for use in the present invention, it is first ground to a finer size than -200 mesh. The pulverized pearlite is then heated to a temperature of about 1500 ° F. This process is done by first heating the air to 1500 ° F. in the pearlite expander. Finely ground pearlite is then introduced into the heated air. Transported by heated air, it is heated and fried like popcorn. Expanded pearlite is a very light substance. But this has many fine grooves and cracks. When it comes in contact with water, it penetrates into these grooves and cracks and enters the cavity filled with the air of the pearlite. Therefore, prior to use to make expanded pearlite into a binder, it must first be treated in a water-free manner. This can be done in one of several ways. The preferred method is to treat the expanded pearlite with a silicone compound that prevents cracks and crevices.

바람직한 실리콘 화합물은 물로희석가능한 폴리디메틸 실록산(poly dimethyl siloxane)의 에멀젼이다. 이 실리콘 화합물은 분무 또는 침지에 의해 팽창 퍼얼라이트에 사용된다. 이 실리콘 화합물은 약 300℉에서 약 5분간 처리된다.Preferred silicone compounds are emulsions of poly dimethyl siloxane dilutable with water. This silicone compound is used in expanded pearlite by spraying or dipping. This silicone compound is treated for about 5 minutes at about 300 ° F.

설비작동에 있어서, 실리콘 화합물은 처리실에 있을때 및 뜨거운 상태에서 팽창된 퍼얼라이트에 사용될 수 있다. 그리고 나서 실리콘 화합물은 상승온도의 결과로써 고온 처리된다. 물에 영향받지 않은 퍼얼라이트가 되게하는 다른 방법은 미국특허3658564에 나타나 있는데, 이에 의하면 퍼얼라이트는 나트륨이나 포타슘실리게이트로 처리하므로써 물에 영향받지 않게된다.In plant operation, silicone compounds can be used in expanded pearlite when in a process chamber and in a hot state. The silicon compound is then hot treated as a result of the elevated temperature. Another method for making water unaffected perlite is shown in US Patent 3658564, whereby the pearlite is not affected by water by treatment with sodium or potassium silicate.

본 발명의 두번째 성분은 충진재(filler)이다. 이분야에서 알려진 어떠한 통상적인충진재도 사용가능하다. 바람직한 충진재는 잘게 분쇄된 탄산칼슘이다. 사용가능한 다른 충진재는 칼슘 설페이트 디하이레이트 및 칼슘설페이트 헤미 하이드레이트이다. 덧붙여서 운모, 활석, 피로필라이트(pyrophylite), 견운모, 규조토 및 고령토 같은 점토를 앞서의 충진재와 함께 사용할 수 있다.The second component of the invention is a filler. Any conventional filler known in the art may be used. Preferred fillers are finely ground calcium carbonate. Other fillers that can be used are calcium sulfate dihydrate and calcium sulfate hemi hydrate. In addition, clays such as mica, talc, pyrophylite, biotite, diatomaceous earth, and kaolin can be used with the preceding fillers.

본 발명의 세번째성분은 비평준화제(non-leveling agent)이다. 바람직한 비평준화제는 점토(attapulgusclay)이다. 그밖의 다른 비평준화제는 아미로팩틴전분(amylopectin starch)을 여러가지 질점토와 개중량비로 5 : 1로 혼합한 혼합체이다. 또 다른 사용가능한 비평준화제는 여러종류의 벤토 나이트이다. 비평준화제는 결합제에 요변성(thixotropicity)같은 일종의 유동적인 성질을 부여한다.The third component of the present invention is a non-leveling agent. Preferred leveling agents are clays (attapulgusclay). Another leveling agent is a mixture of amylopectin starch 5: 1 in various weight clays and weight ratios. Another usable leveling agent is various types of bentonite. Leveling agents impart a kind of fluidity property such as thixotropicity to the binder.

나아가 팽창 퍼얼라이트자체도 상당한 정도로까지 바람직한 유동학적인 성질이 기여한다는 것이 발견되었다. 결합제에 있어서 요구되는 다른 물질은 농조화제이다. 통상의 농조화제는 하이드록시프로필 메틸 셀룰로우즈, 하이드록시 에틸셀룰로우즈, 하이드록시에틸메틸 셀룰로우즈 및 소디움카복시메틸 셀룰로우즈등이다. 농조화제는 단독으로 사용될 수 있고 혹은 상호 연합하여 사용될 수도 있다.Furthermore, it has been found that the expanded pearlite itself contributes to a considerable extent desirable rheological properties. Another material required for the binder is a thickening agent. Typical thickening agents are hydroxypropyl methyl cellulose, hydroxy ethyl cellulose, hydroxyethylmethyl cellulose and sodium carboxymethyl cellulose and the like. Thickening agents may be used alone or in combination with each other.

결합제에 요구되는 다른 성분은, 특히 건조화합물인 경우, 접합재(Binde)이다. 바람직한 접합재는 폴리비닐아세테이트이다. 사용가능한 다른 접합재는 폴리비닐알콜, 에틸렌 비닐 아세테이트공중합체, 비닐 아크릴 공중합체, 스티렌-부타디엔 공중합체, 다른 아크릴 중합체 및 전분이다. 결합제에 일반적으로 사용되는 부가성분은 방부제, 습윤제, 탈거품제 및 가소제이다.Another component required for the binder is a binder, especially when it is a dry compound. Preferred bonding material is polyvinylacetate. Other binders that can be used are polyvinyl alcohol, ethylene vinyl acetate copolymers, vinyl acrylic copolymers, styrene-butadiene copolymers, other acrylic polymers, and starches. Additives commonly used in binders are preservatives, wetting agents, stripping agents and plasticizers.

The difference is that large equipment is used and each component is used in large quantities. In the course of the process, water is first filled in a large mixer. Then adhesive and preservative are added and mixed together. The mixer is then activated and other solids such as clay, calcium carbonate and pearlite are injected into the top of the mixer. These ingredients are mixed together for about 15-20 minutes. At the end of this time additional water is injected and mixed with the composition to match the viscosity of the binder. This material is then loaded into a container for transportation. The composition of the binder is shown in Table II below.

본 발명의 경량 결합제는 선행기술에서 알려진 결합제보다 많은 잇점을 가지고 있다.The lightweight binder of the present invention has many advantages over the binders known in the prior art.

가장 큰 잇점은 물질의 중량이 종래의 결합제보다 가볍다는 것이다. 결과적으로운반비가 절감되는 것이다. 덧붙여서 이러한 중량의 가벼움 때문에, 결합제는 양동이(Bucket), 흙손(trowel) 혹은 바쥬카(bazooka)로 쉽게 옮겨지며 근로자가 쉽게 일을 할 수 있는 것이다.The biggest advantage is that the weight of the material is lighter than conventional binders. As a result, the transportation cost is reduced. In addition, because of this light weight, the binder is easily transferred to a bucket, trowel or bazooka and is easy for the worker to work with.

결합제가 가해지고 건조된 후,이는 종래의 결합제보다 모래치기가 훨씬 쉬우며모래치기후 매끈하게 처리된 벽이 얻어진다.After the binder has been applied and dried, it is much easier to sand than conventional binders and a smoothly treated wall is obtained after sanding.

본 발명의 결합제는 또한 수축율이 낮다는 점에서 통상의 결합제보다 큰 잇점이 있다.The binder of the present invention also has an advantage over conventional binders in that the shrinkage rate is low.

이러한 성질로 인하여, 균열을 피하기위해 통상의 결합제에 사용하는 성분인 활석이나 운모를 사용할 필요가 없다.Due to this property, it is not necessary to use talc or mica, which is a component used in conventional binders, to avoid cracking.

본 발명의 결합제는 뛰어난 접착성 및 뛰어난 도포성을 가진다. 사실상 석고판금속코너비드(beads)를 덮기위하여 종래의 결합제에서 주로 요구되는 통상적인 3번의 도포를 2번도포로 줄일 수 있다는것이 발견되었으며 이로인하여 인력및 재료비 절감이 되는 것이다.The binder of the present invention has excellent adhesion and excellent applicability. In fact, it has been found that the typical three applications required for conventional binders to cover gypsum sheet metal beads are reduced to two coatings, thereby reducing manpower and material costs.
